Its function are principally to protect the plant from injury or adverse conditions and to reduce water loss. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants. Describe the functions of meristematic, xylem and phloem tissue. Xylem is a specialized type of vascular tissue created in vascular plants to transport water and nutrients from the roots of a plant to the tips of the leaves. Vascular tissue is an arrangement of multiple cell types in vascular plants which allows for the transport of water, minerals, and products of photosynthesis to be transported throughout the plant. In flowering plants, both xylem vessels and tracheids, or only vessels are concerned with conduction of water and minerals from roots to the aerial parts of the plant. One xylem and one phloem are known as a ‘vascular bundle’ and most plants have multiple vascular bundles running the length of their leaves, stems, and roots. View Answer.

The intensive variable is water potential, and it describes the intensity or quality of water in plant tissue or soil. Dense fluid found between grana (stacks of thylakoid disks) of a plant cell's chloroplast. Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. Such a parenchyma type is called aerenchyma. Conduction of water occurs by xylem which is a complex permanent tissue. Xylem is meant to conduct water and mineral salts upward from root to the leaf and give mechanical strength to the plant body. Xylem vessels and tracheids are non-living plant tissues that are thick-walled while xylem parenchyma is a living tissue. 3. Plant water relationship. Stroma.

The conducting system: Xylem and phloem compose this system and they are concerned with upward conduction of water and downward translocation of solutes. (1979). As growth proceeds, the cork cambium forms in living cells of the epidermis, cortex, or, in some plants, phloem and produces a secondary protective tissue, the periderm. Water moves through the perforation plates to travel up the plant. Stellate Parenchyma Cells: found in ground tissue in aquatic plants that are composed of star-shaped cells with large intercellular spaces between the arms used as air canals. True.
